Readout of double-sided silicon strip detectors with high density detectors with high density integrated electronics

The authors describe the readout system that has been developed for the ALEPH minivertex detector at LEP. The design makes use of capacitively coupled double-sided silicon strip detectors and custom-designated low-noise VLSI CMOS electronics, mounted on ceramic carriers which simultaneously serve as mechanical support and substrates for thick-film hybrid circuitry. The amplification of as many as 1536 analog channels of information using only 30 input/output lines is realized. The detector system with its peripheral driving and readout electronics is described, and first test results with a light source and a particle beam are given.<
